Motion limitations of non-contact photoplethysmography due to the optical and topological properties of skin [PDF]
, 2016 Non-contact photoplethysmography (PPG) provides multiple benefits over in-contact methods, but is not as tolerant to motion due to the lack of mechanical coupling between the subject and sensor.

An Adaptive Feature Extraction Algorithm for Classification of Seismocardiographic Signals
, 2018 This paper proposes a novel adaptive feature extraction algorithm for seismocardiographic (SCG) signals. The proposed algorithm divides the SCG signal into a number of bins, where the length of each bin is determined based on the signal change within ...

Ecology and Evolution, Volume 14, Issue 6, June 2024.We investigated potential factors affecting embryonic heart rate (EHR), a proxy of development, in 14 wild songbird species in east‐central Illinois, USA. Within species we found that EHR was positively associated with embryonic age and egg temperature, while EHR among species were positively associated with nest predation risk.
